I believe this is a flower and bud from the ericaceous soil loving Camelia or a related genus like Rhododendron or Azalea. This photo was shot at the mediterranean biome of the Eden Project in Cornwall.

Shot at home on a bright red tulip. Converted to black-and-white for clarity. Can you spot a teeny-tiny aphid in the picture? You may wish to see this picture in a larger size on Flickr by clicking on the photo.
